IMPROVEMENT IN SPRING BED'- BOTTOMS.

Specitioation'forming part of Letters Patent No. 113,385, dated April 4,1871; antedated March 27, 1871.

To all 'whom t may concern Be it known that I, LYMAN M. BATES, ofCleveland, in the county ot' Cuyahoga and State of Ohio, have inventedcertain neu7 and useful Improvements in Spring Bed-Bottoms; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing andto the letters of reference marked thereon, Which make a part of thisspecitication.

The nature of my invention consists in a spring bed -bottom, composed ofcanvas or other suitable material drawn over a series of springs, andsecured to a movable frame, or to the bed, and so arranged as todispense With a top frame. It also consists in the construction of theframe to which the canvas may be secured, and in the mode of securingsaid canvas to the frame.

In order to enable others skilled in the art to which my inventionappertains to make and use the sa1ne,I Will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in Which-Iiigure l is a perspective view, part in section, of my bed-bottoni; andFig. 2 is a seetion ot the frame.

A represents a frame of any suitable dimensions, on the upper side ofwhich is secured a series of slats, B B, running across the frame. Onthese slats are placed and suitably fastened any desired number oi'springs C C', over Which the canvas D is drawn, as shown. The canvas Dis cut ot proper size, and at suitable intervals around its edges areinserted eyelets Ya a. When the canvas l) is stretched over the springsC C, audits edges brought down to the outside of the frame A, theseeyelets are fastened on hooks b, which are driven in the frame in agroove, el, formed in its outer side, both on the sides and ends, asshown in Fig. 2. The frame A may then, on the outside, be covered bymolding E, which would entirely hide the edge of the canvas and thehooks.

In place of the hooks b b the canvas `may be fastened by buttons orother suitable means, and it maybe fastened, if so desired, to the beditself, instead of a movable frame.

Having thus fully described my invention,

what I claim as new, and desire to secure byV Letters Patent, is-

1. A spring bed-bottom, consisting of canvas or other suitable materialrdau-'n over a series of springs, and rendered detachable by being hookedor buttoned to the bed or frame, substantially as herein described.

2. The sides and ends ot' the frame when provided with grooves in Whichthe canvas is secured by hooks, buttons, or other suitable means, andwhich grooves may be covered by molding, substantially as described.

In testimony that I claim the foregoing as my own I afiix my signaturein presence ot two Witnesses.
